Application filed June 23, 1906. Serial No. 323,092.

To all, whom, it mag concern:

Be it known that I, ZARDIA GRAIN, a citizen of the United States,residing at Murphysboro, in the county of Jackson, State of Illinois,have invented certain new and useful Improvements in Book-Holders forAdding-Machines, of which the following is a specification, referencebeing had therein to the accompanying drawing.

This invention relates to a book-holder for computing-machines, andparticularly to an attachment adapted for use with-machines of thischaracter.

The invention has for an object to provide a book-holding carriagemounted for travel in both vertical and horizontal planes relative tothe computing-machine towhich it is attached, together with means'forautomatically controlling the movement of said carriage in the operationof the computing-machine. Another object of the invention is to providean improved construction and arrangement of book-holder rovided withplatens ada ted to be inserterf beneath the leaves of the k forretaining the book in proper position Within the carriage.

Other and further objects and advantages of the invention will behereinafter set forth, and the novel features thereof defined by theappended claims.

In the drawings, Figure 1 is a perspective of the invention with thebook-holder removed from the carriage. Fig. 2 is a rear elevationthereof with the book-holder in position. Fig. 3 is a vertical sectionon the line 3 3, Fig. 2. Fig. 4-is a similar view showing thebook-holder removed from the carriage forproper adjustment of the booktherein.

Fig. 1 9 is a similar viewwith this gear thrown out of mesh to receive the frame; and Fig. 20 is adetail elevation of the rear of the carriage, showing the platenssupported thereon. 7

Like numerals of reference indicate like parts throughout the several 7views of the drawings.

The numeral 1 designates a computingmachine, which may be of any desiredcharacter-for instance, the type known as the Burroughs machine, whichis provided with the operating-lever 2 at one side, by

which the printing operation is controlled after the keys 3 have beenproperly operated to set the numerals. In the present ap licaliownassupipprted upon a board or base 4, carried by a ed frame '5, having atits opposite ends standards 6 and 7, the latter being provided with arack 8, as hereinafter described.

The machine may be connected to'this standaid in any desiredmanner-forinstance, by braces9 at opposite sides thereof-and upon thestandards the vertical bars 10 of the carriage-frame 11 are slidinglymounted with the usual ball-bearings, if desired. The top and bottomrails of this frame are connected bythe vertical bars 12, within whichframe the carriage 13 is adapted to travel, thetop and bottom rails 14thereof being grooved to receive the ball-bearings 15, as shown in Figs.

ably mounted on the vertical bars 12 by means of set-screws 16 and 17,the latter extending through anelongated slot in the face I I 3 and 4.The rail 11 of the frame is adiustof the frame-Hand connected by aflexible strip. 19' with a depending hook 20-from the [0O issecured byaracket 19 to the under face I For the purpose of controlling the travelofv the carriage within its frame a column-stop mechanism is providedand is adapted to be automatically controlled from the computlug-machine by means of the crank-arm 21, carried upon an oscillatingshaft 22, extended from the mechanism within the ma chine, and connectedby a link 23 with the angle-arm 24, disposed upon a pivoted bar. 25,which extends for the length of the standard and has its bearings 26 atthe opposite ends thereof. This bar s shown in detail in Fig. 11 and inthe operation of the computing-machine is adapted to swing toward andfrom the standard upon which it is mounted. The free edge of this bar isdisposed in the path of the rock-lever 27, which is pivotally mountedupon the bearing portion 28 intermediate of its ends by means of abearing 29,

applied to the vertical bar of the carriageframe 10, and the upper end30 of this lever connects with the colun'in-stop mechanism, ashereinafter described. The lower end of this bar is provided with acasing, as shown in Figs. 14 and 15, at 31, within which the pawl 32 ispivotally mounted at 33 and provided with an inclined face 34 and astop-lug 35 to limit its outward movement. The pawl is normally held inits outward position, as shownin Fig. 15, by means of a spring 36,carried by the casing and bearing against the under face of the pawl.Beyond this casing a plate 37 is formed and provided with an elongatedslot 38, through which the stop-pin 39 extends, said pin being mountedin the frame and provided with a head 40 to limit the outward swing ofthe rock-lever. It will thus be seen that in the oscillation of the bar25 the rock-lever is swung on its pivot until the bar passes the pawl,and this movement of the rock-lever is communicated to the stopmechanism.

The column-stop mechanism hereinbefore referred to comprises thehorizontally-disposed rod 41, adapted to oscillate in bearings 42 andalso to have a limited reciprocatory movement therein. This rod isprovided with a parallel connecting-pin 43, pivotally connectedwith thefree end of the rock-lever 30, as shown at 44 in Figs. 1 and 11.. Therod 41 is provided with a cushioning-spring 45, bearing at one endagainst a bearing 42 and adapted to be adjusted in tension by thelock-nuts 46, threaded upon the rod. The rod also carries a dog-casing47, within which the dog 48 is pivotally mounted at 49 and normallythrown outward from said casing by means of a tensionspring 50 bearingthereon. This dog 48 is disposed at the lower portion of the casing,while at one side of the casing a secondary dog 51 is provided, which ina swinging movement of the rod is adapted to be throwp into the planepreviously occupied by dog 48, so as to engage one of the column-stops52, any desired number of these-stops being the frame 11.

i tact with the pin 7.4, by which it is held. "It

used, depending upon the number of columns to be printed. These stopsare retained in position upon a slideway 53, extending longitudinally ofthe top rail 14 of the carriage, and which way is provided with a flange54, having an interiorly roughened or toothed face 55, adapted toco6perate with a similar face 56, carried by the flange 57 of the stop.These teeth or engaging faces are preferably disposed diagonally to avertical line, as shown in Fig. 13, so as to retain the stops 52 at anyposition they may be disposedthera on. The casing 47 is normally thrownoutward from the carriage-frame 11, upon which it is mounted, by meansof a spring 58 at. the rear thereof, which spring in its action alsorestores the rock-lever 27 to its initial position. From the abovemechanism it will be seen that an oscillation of the dogcasing 47 in onedirection will carry the dog 48 out of engagement with the first stop 52and permit a movement of the carriage until the second stop engages thesecondary dog 51, by whicli the carriage is held until the casing isrestored to its normal position, when this second stop will move intoengagement with the dog 48 in position for a subsequent operation.

For the purpose of controlling the vertical movement of the carriageline by line the frame 11, carrying the same, is slidingly mounted uponthe standards, as before described, the standard 7 being provided withthe rack 8, as shown in detail in Figs. 16, 17, 18, and 19, with which apinion 60 is adapted to mesh, said pinion being also in mesh with thegear 61, mounted upon the, fixed part or standard 10 by means of abearing-bracket 62. The shaft of this gear is-provided with anescapement-wheel 63, adapted to co6perate with the dog mechanism 64 ofordinary construction, the shaft 65 of-which carries at its rear atrip-lever 66, having oppositelyinclined faces 67 and 68 and normallyheld at one extreme of its travel by means of a no tension-spring 69,extending therefrom to This trip-lever is adapted to be engaged by oneor more stops 70, pivotally mounted upon the top rail 14 of the carriageat 71 and extending into the path 115 of the trip-lever, whilethelowerend thereof abuts against/the stop-lug 72. A plurality of these stopsare provided in order that theproper spacing between lines may bedetermined. For instance, as here shown, two stops may be used to effecta full space, while if a half-s acing is desired in order to interlineone o the stops maybe thrown, out ofoperative position, and thus held bymeans'of apivoted arm 73, adapted to lie beneath the stop, as shown atthe right of Fig. 16, and in contact with the'stop-lug 72, while ifthe'stop is to be used this arm is thrown away from the lug 72 and inconone tooth of the escapement-whecl.

, at the front of the machine.

' ried by the frame.

will thus be seen that each movement of the trip-lever will oscillatethe dog 64 to produce a downward feed of the carriage for \Vhen it isdesired to operate these dogs by hand, the same can be readily ell'cctedby means of the hand-lever 75, applied to the shaft 65 carriage andparts supported thereby are to be restored to their initial position,the pinion 60 may be disengaged from its rack 8 by means of the lever76, upon which the same is mounted at the lower end, said lever havingits pivot upon the shaft of the gear 61 and being held normally undertension by means of the spring 77, and it will be seen that acompression of this spring will throw the pinion 60 away from the rack.In order to maintain a proper relation of these parts, a bearing-wheel78 is carried by the bracket. 79 upon the carriagefr'ame to. engage therear face of the standard. It will be observed that the vertical feed ofthe book i brackets 83, carried by thelower rail of the carriage, saidbrackets being provided with an elongated bearing-recess 84, as shown inFig. 3, whereby a pintle may be removed from the bearings by alongitudinal movement therein. This frame is adapted to receive the bookand is provided at its pivot end with a cross rod or bar 85, mounted inthe side walls of the-frame and in the bracket 86 ,carried thereby, uponwhich the platens 87 are pivoted at each side of the bar 88, car- The seplatens are provided with pivotingbearings 89, as shown in Fig. 8, andare mounted upon the carria e, as shown in Fig. 4, so as to lie beneatht e sheet of the bookwhich is to receive the impression from thecomputingmachine. The platens are each tapered in cross-s'ectiontowardthe central bar 88, as shown in Fig. 10, so as to place their smallestdiameter next the bound edge of the sheet. In other I words, they taperinwardly toward the center'of, the frame. Upon the extended ends 90 ofthe rods the casing 91 is mounted by means'of the elongated slots 92 inthe side walls thereof, said casing being provided with the central bar93 in alinementwith the bar 88 and extending from a cyossbar94.

The casing fits snugly over the frame and.

is provided with a lug9-5 to 'limit its movement relative to thecarriage, as shown in \Vhen the 5 Figs. 3 and 4. This casing holds thesheet to receive the printing firmly against the platens.

The book-holder and parts carried thereby are adapted to be raised intothe printing po sition (shown in Fig. 3) in the carriage by means of thetension-arm 96, pivotally mounted at 97 upon the lug 98, carried by 3the bar 14 of the carriage, said arm being provided with a stop-lug 99,adapted to en gage a cross-bar 100, carried by the frame below the track.or way thereof. The upper end of this arm is pivotally connected at 101to a sleeve 102, 'slidingly mounted upon the rod 103, carried bybearings 104 upon the bar 88 of the frame 80. The coil-spring 105extends from one of these bearings to the sleeve 102, so that when thebook-holder is lowered into the position shown in Fig. 4 the spring isplaced under tension. When in this position, the holder is adapted to belocked and held against the automatic raising by the spring by means ofthe pivoted catch 106,.mounted on the side of the bar 88 and adapted toengage the to0th'107, carried by the sleeve 102, and normally held incontact with said tooth. by the spring 108 hearing upon the latch. Thecrank-arm 109 from this latch is connected by rod 110 with theoperating-lever 111, pivotally mounted at 112 upon the bar and adaptedto cooperate with the fixed handle 113, carried by the holder-frame.When it is desired to raise the carriage into the position shown in Fig.3, it is only necessary to release the latch 106, and the spring willthrow the book-holder upward into engagement with the carriage, theposition of the tension-arm being such as to prevent a return movementexcept when drawn backward by an exterior force.

The book, as shown at 114 in Figs. 3 and 4, is supported upon backboards 115, Figs. 2 and 3', these boards being provided at opposite endswith the crossed levers 116,..Fig. 5, pivotally mounted at 1 17 upon theboard-and at 118 upon the frame 80, while the .opposite ends of theselevers have a sliding and pivotal bearing at 119 on the .board' and 120on the frame; These levers provide for the movement of the boards towardand from the casing of the book-holder in parallelism, the levers beingpivoted togetherat their point of crossing 121. The boards are normallypressed inward toward the casing by means of the spring-levers 122, asshown in Fig. 2, having a bearing 123 at the center of the boardsand'adjustably secured to the tension-heads 124, which are mounted uponthe rods 12 5, carried by the brackets 126 of the frame 80, saidheadssbeing retained under tension by means of thecoil-spring 127, consnected thereto at one endme'aring against the frame at its opposite end.If it is desired to use he attachment without the book-holder,

the samecan be" readily removed from the carriage and anordinary platen129 of any desired construction mounted upon the brackets 130, carriedby the rear of the carriage-frames 13, as shown in Figs. 1 and 20. Inthe operation of the machine when it is desired to apply a book theretothe holder is swung downward, as shown in Fig. 4, and the casing andplatens thereof swung upward to permit the placing of the book upon theback boards. The platens are then swung into contact with'the book withthe pages to be printed upon the top of the platens and the casingclosed, so as to hold the book in smooth firm contact, owing to thetension of the back boards against the frame and casing. The latch isthen released, permitting the bracket of the tension-arm toautomatically throw the book-holder into vertical position within thecarriage. The carriage frame is then raised, so as to bring the bottomline of the book in printing position, and the carriage moved to theextreme right of its travel. The keys of the computing ma chine are thenoperated to set up the proper numerals to be printed, and upon theoperation of the lever of such machine the printing mechanism thereof isthrown into contact with the book in the usual manner. In the returnmovement of this lever the pivoted bar carried by the standards isoscillated, which in turn operates the columnstop dogs, permitting thecarriage to move to the left into the next position for printing. Thiscontinues for the desired numbef of columns to be printed and effects anautomatic feed of the carriage by the usual operation of thecomputing-machine. In the return movement of the carriage from left toright the stops carried thereby actuate the trip-lever, which operatesthe escapement mechanism controlling the rack and pinion to permit theproper downward movement of the carriage-frame and book carried therebyinto the next lowest position for printing. It will thus be seen thatthe book while supported in a vertical position is adapted to receivethe impression from the computingmachine and also the totals or resultsordinarily obtained in the operation of such a machine. The constructionand arrangement of parts is particularly adapted to render the feed ofthe carriage in both a horizontal and vertical plane automaticallyrelative to the machine to which it is attached, while the book-holdingmeans effectually presents the sheet thereof to be printed in properposition to receive the impressions from such a machine.
